Adoboli, 38, who was found guilty in 2012 of fraud that lost his Swiss bank $2.3bn (£1.8bn), is being deported to Ghana because he is not a British citizen despite living in the UK since the age of 12.

Appealing to Sajid Javid and Theresa May to “show some compassion” and intervene.

In an interview with the Guardian from his detention centre, he said, “I did four years in prison for a non-violent act.”

“I’ve served my time, but I’m being given an extra punishment – a banishment – and just because I didn’t get around to becoming a citizen. This punishment is so much worse than being in prison.”

He was released from prison on probation in 2015 after serving half of a seven-year sentence. Last week he was detained at Dungavel immigration removal centre in Scotland. On Wednesday he was transported to Colnbrook immigration removal centre, close to Heathrow.

Campaigners fighting against Adoboli’s deportation said they understood the Home Office had booked a charter flight for deportation to Ghana on 18 September and said Adoboli is “earmarked to be on this plane”.

A spokesperson for the Home Office declined to speak about Adoboli’s case but said: “All foreign nationals who are given a custodial sentence will be considered for removal. Foreign nationals who abuse our hospitality by committing crimes in the UK should be in no doubt of our determination to deport them and we have removed more than 43,000 foreign offenders since 2010.”

Adoboli’s MP, Hannah Bardell, and 113 other MPs and MSPs have written to the prime minister and home secretary to demand they intervene to stop Adoboli’s deportation.

“If Mr Adoboli were deported, he will be removed from the country he has called home since the age of 12, taken away from the close relationships he has formed here and returned to a country he has not lived in from the age of four and lacks familiarity with,” Bardell said in the letter.

“The recent comment by former home secretary, Amber Rudd MP, that ‘the Home Office has become too concerned with policy and strategy and sometimes loses sight of the individual’ is apt in this case and we are sure no one in the cabinet wishes to have another ‘Windrush Generation’ scandal on their hands anytime soon.”
